Three months after he graduated from drama school, in his first audition Bradley won the part of
Samwell Tarly in the 2011
HBO fantasy TV series
Game of Thrones, whom he would play for all 8 seasons of the show. His character is a friend of
Kit Harington's
Jon Snow and provides occasional
comic relief, especially in
season 1. As the series progressed, Bradley's Tarly developed significantly. One reviewer called him "a wonderful comedic and cowardly
yin to Jon's dour
yang".
George R. R. Martin said that the character that Bradley portrays is the character he would be, if he were on the show. In 2011, Bradley appeared in the
Canal+ drama,
Borgia, in the role of
Giovanni di Lorenzo de' Medici, the future
Pope Leo X. The same year, he appeared on the
Channel 4 TV series
Shameless in the role of Wesley,
Frank Gallagher's boss, in two episodes of series 10. In 2018, Bradley appeared as Scooter in the film
Patient Zero, with fellow
Game of Thrones performer
Natalie Dormer. In 2022, he was one of the leads in the
Roland Emmerich disaster film
Moonfall and played a supporting role in the romantic comedy
Marry Me, starring
Jennifer Lopez and
Owen Wilson. ==Personal life==
